DETAILED DESCRIPTION OF STRUCTURE A preferred embodiment of the new safety container and closure cap unit therefor is illustrated in the drawings, wherein it is generally indicated at and comprises a generally cylindrical container body 31 having a generally annular upper end or neck portion 32 and a safety closure cap unit generally indicated at 33, and which is adapted to be detachably mounted on the generally annular upper end or neck portion 32 of the container body 31; it being understood that the container body 31 and its upper end or neck portion 32 may take various forms and shapes and sizes or dimensions.

The closure cap unit 33 comprises a generally cylindrical outer body member 34 and a generally annular inner body member 35 which are detachably assembled together for installation upon and removal from the neck portion 32 of the container body 31, as will be described more fully hereinafter.

The outer body member 44 and the inner body member 35 of the closure cap unit 33 may be made of any suitable materials as, for example, molding the same from any suitable synthetic resinous plastic molding material such, for example, as polystyrene, polyethylene, synthetic rubberlike copolymer elastomers, glass, metal, or the like, and the container body 31 and its neck portion 32 may likewise be made of any suitable material such, for example, as glass, metal, synthetic rubberlike copolymer elastomers, synthetic resinous plastic materials, and the like.

The upper end or neck portion 32 of the container body 31 has a first latching or attaching means formed therein as an integral part thereof for detachably latching or attaching the closure cap unit 33 on and to the neck portion 32 of the container body 31. Likewise, the upper end or neck portion 32 of the container body 31 has a pair of combination guide and camming means formed therein, each of which is generally indicated at 36 (FIG. 7) and includes a pair of irregularly shaped or curvilinear combination guide and camming slots 38 which are spaced circumferentially approximately on the neck portion 32 of the container body 31 (FIG. 11). Each of the combination guide and camming slots 38 has at one end thereof an inlet-outlet 39 which opens at its upper end on the top or upper edge portion 69 of the neck portion 32 of the container body 31. At its other and lower end each of the combination guide and camming slots 38 has an upwardly and generally vertically extending portion in the form of a latching recess 41, the upper end portion 42 of which terminates below the top or upper edge 40 of the upper or neck portion 32 of the container body 31; the latching recesses 41 providing the first attaching or latching means which is embodied in the new combination container and closure cap unit therefor for detachably attaching the closure cap unit 33 to and upon the upper end or neck portion 32 of the container body 31.

A pair of irregularly shaped curvilinear camming surfaces 53 are thus provided in the upper end or neck portion 32 of the container body 31 above the combination guide and camming slots 38, and an additional curvilinear cam surface is provided by the upper edge portion 68 of each of the combination guide and camming slots 38 (FIG. 7).

The inner body member 35 of the closure cap unit 33 includes a generally annular body 43 which includes a generally annular side wall 44 and a top wall 45. The inner body member 35 also includes a second latching or attaching means in the form of a plurality, shown as a pair, of resilient depending latching or attaching tongue members 46 which are formed integrally with and depend from the generally annular side wall 44 thereof at spaced radial intervals of preferably 180 thereon, each of the resilient latching or attaching tongue members? 46 having a radially inwardly extending lower latching (ir attaching end portion 47 (FIGS. 6, 12, 15, 16, 17,

The inner bodvih'ember 35 OF-1IIB-CIOSUI C3Q I1I I II33 has a plurality, shown as a pair, of manually operable unlatching members 48 which are formed integrally therewith on the outer side of the generally annular side wall 44 thereof and at spaced intervals of preferably 180 radially therearound. Each of the manually operable unlatching members 48 projects radially outwardly of the generally annular side wall 44 of the inner body member 35 and an upwardly extending recess 49 is formed in the inner body member 35 of the closure cap unit 33 between each of the manually operable unlatching members 48 and an adjacent motion limiting restraining means in the form of a wall portion 50 of the generally annular side wall 44 of the inner body member 35, for a reason which will be pointed out presently (FIGS. 4, 12, 15, 16, 17 and 18). Each of the restraining wall portions 50 of the generally annular side wall 44 of the inner body member 35 of the closure cap unit 33 and each of the adjacent manually operable unlatching members 48 has a flexible interconnecting web portion 52 by which it is joined at its upper end to the generally annular side wall 44 of the inner body member 35 of the closure cap unit 33, immediately below the top wall 45 of the inner closure body member 35, and the flexibility of each of the restraining wall portions 50 and of the adjacent manually operable unlatching members 48 is enhanced by the provision ofa pair of vertically extending slots 52 which are formed in the generally annular side wall 44 of the inner closure body member 35 at the sides of each of the manually operable unlatching members 48 (FIGS. 2 and 19).

The outer body member 34 of the closure cap unit 33 iricludes a generally annular side wall 54 and a transversely or horizontally extending sealing wall 55 which extends across the outer closure body member 34 between the upper and lower ends thereof (FIGS. 4, 5, 6, 8, 9, 10, 13, 15, 16, 17,24

and 25). The generally annular side wall 54 of the outer closure body member 34 has a pair of vertically extending slots 56 formed therein which are spaced apart circumferentially on the generally annular side wall 54 of the outer body member 34, a distance corresponding to the spacing of the manually operable unlatching members 48, that is, preferably 180. Each of the manually operable unlatching members 48 on the inner body member 35 of the closure cap unit 33 projects through and works in a corresponding one of the slots 56 in the generally annular side wall 54 of the outer body member 34 when the inner body member 35 and the outer body member 34 of the closure cap unit 33 are assembled together. As shown in FIGS. 2 and 22, the slots 56 in the generally annular side wall 54 of the outer closure body member 34 open at their upper ends at the upper edge 57 of the generally annular side wall 54 of the outer closure body member 34.

As shown in FIGS. 6, 9, 10, 15, 16, 17 and 25, each of the manually operable latching or attaching members 46 on the inner closure body member 35 projects downwardly through and is vertically slidably movable in a slot 58 which is formed in the transverse horizontal sealing wall 55 of the outer closure body member 34. A pair of upwardly extending stop or restraining boss and cam members 61 are formed on the generally horizontal or transverse sealing wall 55 of the outer body member 34 and these restraining boss members 61 are disposed in alignment with the manually operable restraining members 50 on the inner closure body member 35 when the inner end outer body members 35 and 34, respectively, of the closure cap unit 33 are in assembled relationship, as shown in FIGS. 4 and 15. Each of the combination restraining boss and cam members 61 has a downwardly and inwardly extending cam surface 71 formed on its inner surface, for a reason which will be pointed out hereinafter (FIGS. 4, 13, 15, 16, 17 and 25).

As shown in FIGS. 4, 5, 6, 13, l5, 16, 17 and 25, the generally annular side wall 54 and the horizontal or transverse sealing wall 55 of the outer body member 34 of the closure cap unit 33 cooperate to provide a generally cylindrical cavity or recess 60 for the reception of the inner body member 35 of the closure cap unit 33 when the inner body member 35 and the outer body member 34 are in assembled relationship.

The top wall 45 of the inner closure body member 35 has a centrally arranged finger grip or finger-receiving portion 62 formed therein, which provides one of the three manual pressure points which are located at spaced intervals on the peripheral surface of the closure cap unit 33, for a reason which will be pointed out hereinafter.

A radially inwardly extending guide member in the form of a boss 63 is formed integrally with and is an extension of the generally annular side wall 54 of the outer body member 34 of the closure cap unit 33 below the transverse or horizontal sealing wall 55 thereof and at one side of the corresponding slot 58, the bottom surface of each of these guide members 63 being substantially coplanar with the bottom surface of the generally annular side wall 54 of the outer closure body member 34 (FIGS. 13, and

The radially inner surface of the generally annular side wall 54 of the outer closure cap body member 34 is dished out to provide a pair of radially outwardly extending recesses 64 therein, each of these recesses 64 being in vertical alignment with and being disposed radially outwardly of the corresponding one of the slots 58 in the transverse or horizontal wall 55 in the outer closure cap body member 34 (FIGS. 6, 10, 13, 15, l6, l7 and 25) for a reason which will be pointed out hereinafter.

A pair of vertically extending slots 65 are formed in the generally annular side wall 54 of the outer closure body member 34, radially outwardly of but in generally vertical registration with the vertically extending slots 58 in the transverse or horizontal sealing wall 55 of the outer closure body member 34, the lateral edges of each of these slots 65 being defined by a vertically extending surface 66 of one of the guide members 63 and an adjacent vertically extending surface 67 of the generally annular side wall 54 of the outer closure body member 34 (FIGS. 10 and 24). As best shown in FIGS. 10 and 24, each of the vertically extending slots 65 in the outer side wall 54 of the outer closure body member 34 is closed at its radially outer end by a relatively thin wall portion 71 of the generally annular side wall 54 of the outer closure body member 34, each of the relatively thin wall portions 71 being disposed radially outwardly of the corresponding one of the radially outwardly extending recesses 64 (FIG. 10).

OPERATION In the use of the new safety container and closure cap unit therefor the generally annular inner closure body member 35 is manually assembled within the generally cylindrical cavity or recess 60 in the generally cylindrical outer body member 34, and the resilient latching or attaching arm members 4647 are projected downwardly through the slots 58 in the transverse or horizontal sealing wall 55 of the outer body member 34 and with the manually operable unlatching members 48 being disposed in and projecting outwardly of the vertically extending slots 56 in the generally annular side wall 54 of the outer closure body member 34.

When the inner body member 35 and the outer body member 34 of the closure cap unit 33 are thus assembled the lower and radially inwardly extending latching end portions 47 of the flexible, resilient latching or attaching members 46 project downwardly through the slots 58 in the transverse or horizontal sealing wall 55 of the outer closure body member 34 with the radially inwardly extending lower end portions 47 of the flexible, resilient latching or attaching members 46 disposed in the slots 65 which are formed in the generally annular side wall 54 of the outer closure body member 34 between the vertically extending surfaces 66 of the guide members 63 and the vertically extending surfaces 67 of the generally annular side wall 54 of the outer closure body member 34 (FIG. 10). When the inner closure body member 35 and the outer closure body member 34 of the closure cap unit are thus assembled the lower surfaces of the inwardly extending lower end portion 47 of the flexible, resilient latching or attaching members 46 are disposed in a generally horizontal plane which lies immediately above the upper horizontal surfaces of the guide members 63 (FIG. 15).

When the inner and outer closure body members 35 and 34, respectively, of the closure cap unit 33 are thus assembled the assembled closure cap unit 33 may be inserted upon and detachably latched or attached to the upper end or neck portion 32 of the container body 31 by manually aligning the flexible resilient latching or attaching members 46-47, and the guide members 63, with the upper end or inlet-outlet portions or mouths 39 of the combination guide and camming slots 38 which are formed in the neck portion 32 of the container body 31 (FIG. 7) and then manually pressing downwardly on the closure cap unit 33 so as to project the guide members 63 downwardly into and through the inlet or mouths 39 of the combination guide and camming slots 38. The assembled closure cap unit 33 may then be readily manually latched or attached to the neck portion 32 of the container body 31 by imparting rotational movement in the form of a partial turn or revolution thereto, (counterclockwise, FIGS. 7, 8 and 9) thereby causing the guide members 63 to travel in the curvilinear combination guide and camming slots 38 from their inlet portions or mouths 39 toward their outlet ends 36 (FIG. 7). During this movement the lower and inwardly extending latching or attaching end portions 47 of the flexible resilient latching or attaching members 46 engage and ride over the radially outer cam surfaces 53 which are formed on the peripheral surface of the neck portion 32 of the container body 31, thereby forcing the lower and latching or attaching end portions 47 of the flexible resilient latching or attaching members radially outwardly in the slots 65 while, at the same time, forcing the flexible resilient latching or attaching members 47 radially outwardly in the slots 58 in the transverse or horizontal sealing wall 55 of the outer closure body member 34, and thereby placing the flexible resilient latching or attaching members 46-47 under tension.

Accordingly, when the flexible resilient latching or attaching members 46-47 reach the outer end portions 36 of the curvilinear combination guide and camming slots 38 in the neck portion 32 of the container body 31, the radially inwardly extending and then tensioned lower latching or attaching end portions 47 of the flexible, resilient, latching or attaching members 46-47 move or snap under their own tension and resiliency radially inwardly into the upwardly extending latching recesses 41 in the curvilinear combination guide and camming slots 38, and into engagement with the upper edge portion 42 thereof, thereby detachably latching or attaching the assembled closure cap unit 33 to and upon the neck portion 32 of the container body 31 (FIGS. 4, 5, 6 and When the closure cap unit 33 is thus assembled upon and detachably latched or attached to the neck portion 32 of the container body 31, as shown in FIGS. 4, 5, 6 and 15, the closure cap unit 33 cannot be manually removed from the neck portion 32 of the container body 31 by manually pulling upwardly thereon for the reason that the inwardly extending lower latching or attaching end portions 47 of the flexible, resilient latching or attaching members 46 are engaged in the upwardly extending latching recesses 41 at the outer ends of the combination guide and camming slots 38 and abut against the upper edge portions 42 thereof (FIGS. 7 and 15).

It will be noted that when the closure cap 33 is thus installed upon and latched or attached to the neck portion 32 of the container body 31 the restraining members 50 on the radially inner surface of the generally annular side wall 54 of the upper closure body member 35 are disposed in abutting engagement with the corresponding restraining or stop members 61 which are formed on the upper surface of the transverse or horizontal sealing wall 55 of the outer closure body member 34 so that the inner closure body member 35 cannot be moved downwardly relative to or separated from the outer closure body member 34 and the inner closure body member 35 cannot be moved upwardly relative to the outer body member 34 by reason of the latching or attaching engagement of the inwardly extending lower end portions 47 of the flexible, resilient latching or attaching members 46 (on the inner closure body member 34) in the latching recesses 41 in the upper end or neck portion 32 of the container body 31.

As the closure cap unit 33 is thus assembled on and detachably latched or attached to the neck portion 32 of the container body 31, the guide members 63 on the outer closure body member 34 travel through the curvilinear combination guide and camming slots 38 and engage the curved upper camming edge surfaces 68 thereof, thereby exerting a camming action on the closure cap unit 33 and thus forcing the central portion of the transverse or horizontal sealing wall 55 of the outer closure body member 34 downwardly into fluid-tight sealing engagement with the upper edge portion 40 of the neck portion 32 of the container body 31.

It will be noted that whereas the closure cap unit 33 may be readily installed upon and detachably latched or attached to the neck portion 32 of the container body 31 by the simple operation of manually applying the closure cap unit 33 over and onto the neck portion 32 of the container body 31 and then manually imparting rotational movement in the form of a partial turn or revolution thereto, and without the need for or use or manipulation of any manually operable instrumentalities or parts on either the closure cap unit or in the neck portion of the container body, or other operation, the removal of the closure cap unit 33 from the neck portion 32 of the container body 31 requires that the container body 31 be held in one hand while manual pressure is applied simultaneously with the fingers of the other hand to a plurality of manually operable members 48-48-62 located at a plurality of pressure points 48-48-62 (shown as three) spaced from each other on the peripheral surface of the closure cap unit 33, as will be described presently.

Thus, when it is desired to remove the assembled closure cap unit 33 from the neck portion 32 of the container body 31, this may be accomplished by holding the container body 31 in one hand and applying manual pressure simultaneously with the fingers of the other hand to the three pressure points provided by the manually operable members 48-48-62, which are spaced from each other on the peripheral surface of the closure cap unit 33, that is, by applying manual downward pressure with one finger of the said other hand on the central portion or pressure point 62 of the top wall 45 of the inner closure body member 35 while, at the same time, applying manual pressure radially inwardly with two other fingers of the said other hand on the manually operable unlatching members and pressure points 48-48.

When manual pressure is thus applied simultaneously on the three manually operable members and pressure points 48-48-62 the radially inward pressure thus applied to the unlatching members 48 forces the adjacent restraining members 50 radially inwardly out of abutting engagement with the restraining members or bosses 61 which thereupon enter the recesses 49 which are formed between the manually operable unlatching members 48 and the restraining members 50, (FIGS. 4, 12, 16 and 17), while, at the same time, the downward manual pressure thus applied on the top wall 45-62 of the inner closure body member 35 forces the inner closure body member 35 axially inwardly. This action moves the inwardly angled and latching or attaching members 46-47 axially downwardly out of latching or attaching engagement in and with the latching recesses 42 and into alignment with the combination guide and camming slots 38.

Rotational movement in the form of a partial turn or revolution is then applied manually with the said other hand to the closure cap unit 33, while still applying manual pressure to the three pressure points 62-48-48 with the fingers of the said one hand. This action causes the radially inwardly angled lower end portions 47 of the flexible resilient latching or attaching members 46 to move or rotate in the combination guide and camming slots 38 (left to right, FIG. 7), and during this movement the radially inwardly extending lower and latching end portions 41 of the flexible resilient latching or attaching members 46 and the guide members 63 on the radially inner surface of the generally annular side wall 54 of the outer closure body member 34 travel in the combination guide and camming slots 38 until they reach the inlets-outlets or mouths 39 thereto, whereupon the assembled closure cap unit 33 may then be manually lifted upwardly off the neck portion 32 of the container body 31; the guide members 62 and the lower latching or attaching end portions 47 of the flexible, resilient latching or attaching members 46 passing upwardly through the upper end portions or inlets-outlets 39 of the combination guide and camming slots 38.

When radially inward manual pressure is thus applied to the flexible manually operable unlatching members 48, these manually operable unlatching members 48 and the adjacent restraining members 50 on the generally annular side wall of the inner closure body member 35, flex or bend inwardly at their flexible web connections 51 with the side wall 44 of the inner closure body member 35, During this operation the flexible restraining members 50 on the generally annular side wall 44 of the inner closure body member 35 ride down the tapered inner cam surfaces 70 of the combination restraining and cam members 61, thereby placing the manually operable unlatching members 48 and the adjacent restraining members 50 under tension. However, when manual pressure is released from the central area 62 of the top wall 45 of the inner closure body member 35 the then tensioned flexible, resilient restraining members 50 ride upwardly under the force of their own resiliency and the tension applied thereto, off the cam surfaces 70 of the combination restraining and cam members 61-70, whereupon the manually operable unlatching members 48 and the attached restraining members 50 will flex at the flexible web portion 51 back into their normal or initial position, as in FIG. 4.

It will be noted that the closure cap unit 33 of the new safety container and closure cap unit therefor may be assembled with and upon the upper end or neck portion 32 of the container body 31 by a simple manual movement of the closure cap unit 33 axially downwardly onto the neck portion 32 of the container body 31 followed by rotational movement in the form of a partial turn or revolution of the closure cap unit 33 in generally the same manner as is employed in installing the conventional screw-threaded closure cap upon a conventional screw-threaded neck portion of a conventional bottle or like container, without the need for or manipulation of any manually operable parts or instrumentalities on either the closure cap unit or the neck portion of the container body, other than rotational movement of the closure cap unit itself, thereby enhancing and facilitating not only the use of the new combination container and safety closure cap unit therefor, but also facilitating and simplifying the operation of assembling the parts thereof on conveyors and in packaging lines in manufacturing plants and like places during the operation of filling the container body 31 and applying the new safety closure cap unit 33 thereto.

Likewise, it will be noted that when the new safety closure cap unit 33 is assembled upon and latched or attached to the neck portion 32 of the container body 31, the closure cap unit 33 cannot be removed from the container body 31 by small children for the reason that to remove the closure cap unit 33 from the neck portion 32 of the container body 31, requires the simultaneous application of manual pressure with the fingers of one hand at a plurality of pressure points 48-48-62 on the periphery of the closure cap unit 33 and imparting rotational movement thereto while, at the same time, holding the container body 31 with the other hand, and small children cannot readily perform the operations thus required to remove the closure unit 33 from assembled and latching or attached engagement with the neck portion 32 of the container body 31.

It will thus be seen from the foregoing description, considered in conjunction with the accompanying drawings, that the present invention provides a new and improved safety container and closure cap unit therefor having the desirable advantages and characteristics, and accomplishing its intended objects including those hereinbefore pointed out and others which are inherent in the invention.
